Alicia Keys, Pharrell and Kendrick Lamar have all teamed up to help watch the city of New York -- oh, and also perform -- in their music video for 'It's On Again,' a powerful tune written for 'The Amazing Spider-Man 2.'

Going once, going twice… sold! Fast food chain Arby's were the highest bidder on Pharrell's infamous Grammys hat, which he sold on eBay to benefit his charity, One Hand to Another. The ten-gallon Vivienne Westwood hat sold for $44,100.
